Download or read book Stream Hydrology written by Nancy D. Gordon and published by John Wiley & Sons. This book was released on 2013-05-03 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition (1994) there have been rapid developments in the application of hydrology, geomorphology and ecology to stream management. In particular, growth has occurred in the areas of stream rehabilitation and the evaluation of environmental flow needs. The concept of stream health has been adopted as a way of assessing stream resources and setting management goals. Stream Hydrology: An Introduction for Ecologists Second Edition documents recent research and practice in these areas. Chapters provide information on sampling, field techniques, stream analysis, the hydrodynamics of moving water, channel form, sediment transport and commonly used statistical methods such as flow duration and flood frequency analysis. Methods are presented from engineering hydrology, fluvial geomorphology and hydraulics with examples of their biological implications. This book demonstrates how these fields are linked and utilised in modern, scientific river management. * Emphasis on applications, from collecting and analysing field measurements to using data and tools in stream management. * Updated to include new sections on environmental flows, rehabilitation, measuring stream health and stream classification. * Critical reviews of the successes and failures of implementation. * Revised and updated windows-based AQUAPAK software. This book is essential reading for 2nd/3rd year undergraduates and postgraduates of hydrology, stream ecology and fisheries science in Departments of Physical Geography, Biology, Environmental Science, Landscape Ecology, Environmental Engineering and Limnology. It would be valuable reading for professionals working in stream ecology, fisheries science and habitat management, environmental consultants and engineers.

Download or read book Critical Realism Environmental Learning and Social Ecological Change written by Leigh Price and published by Routledge. This book was released on 2015-12-14 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southern Africa, where most of these book chapters originate, has been identified as one of regions of the world most at risk of the consequences of environmental degradation and climate change. At the same time, it is still seeking ways to overcome the century long ravages of colonial and apartheid impositions of structural and epistemic violence. Research deliberations and applied research case studies in environmental education and activism from this region provide an emerging contextualized engagement that is related to a wider internationally articulated quest to achieve social-ecological justice, resilience and sustainability through educational interventions. This book introduces a decade of mainly southern African critical realist environmental education research and thinking that asks the question: "How can we facilitate learning processes that will lead to the flourishing of the Earth’s people and ecosystems in more socially just ways?" The environmental education research topics represented in this book are wide-ranging. However, they all exhibit the common theme of social justice and wanting to create change towards a better future. All the authors have used critical realist or critical realist-influenced research methodologies. Offering contributions from a small but growing community of researchers working with critical realism in the global South, this book will be of interest to students, scholars and practitioners in the areas of environmental education, sustainability, development and the philosophy of critical realism in general.
Download or read book Digitally improving the identification of aquatic macroinvertebrates for indices used in biomonitoring written by Koen, R. C. J. and published by International Water Management Institute (IWMI). CGIAR Initiative on Digital Innovation. This book was released on 2023-12-31 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides an overview of the mini Stream Assessment Scoring System (miniSASS) and South African Scoring System Version 5 (SASS5) as biomonitoring techniques for assessing the ecological condition of streams and rivers based on the identification of aquatic macroinvertebrates. While miniSASS relies on minimally trained citizen scientists to identify macroinvertebrates at the Order-level, SASS5 utilizes expertly accredited practitioners for finer resolution, even up to the family-level. However, the reliance on citizen scientists for miniSASS identification introduces limitations in terms of precision, accuracy, and reliability. To address these limitations, ongoing developments within the CGIAR Initiative on Digital Innovation include the creation of a miniSASS smartphone application, an upgraded website, an interactive online course, and a machine-learning identification algorithm to assist with photo identification. Additionally, a revised dichotomous key has been developed to improve operator identification during miniSASS surveys. Furthermore, the potential for upscaling the machine-learning identification algorithm to assist in identifying the 91 family-level taxa used in SASS5 assessments has been explored. The outcomes of these developments and explorations presented in this paper aim to enhance the overall effectiveness and reliability of both the miniSASS and SASS5 techniques. By leveraging digital innovation and incorporating machine-learning technology, we anticipate the efficiency, accuracy, and accessibility of biomonitoring assessments will significantly improve, ultimately contributing to a better understanding and management of our aquatic ecosystems.

This book was released on 2016-11-12 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new way of looking at and analyzing policies, programs and/or plans in which research scientists have used their knowledge to develop mechanisms such as South Africa's National Water Resource Strategy, Second Edition; Australian and South African climate change adaptation strategies for government entities and the UNDP's Water and Ocean Governance focus area. It critically assesses how science can be used in the service of society and how researchers and practitioners can bridge the gaps that arise as a result of incomplete thinking. Presenting a bird’s-eye view of how thinking and understanding operate in the policy context, it offers a valuable contribution to fields of inquiry such as research methods, comparative analyses, political science, international relations and the natural and social sciences in general. This book fills a market gap, providing real-world solutions to the practical application of science, paradigms and theories.
Download or read book The Science of Instream Flows written by National Research Council and published by National Academies Press. This book was released on 2005-04-18 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across the United States, municipalities, counties, and states grapple with issues of ensuring adequate amounts of water in times of high demand and low supply. Instream flow programs aim to balance ecosystem requirements and human uses of water, and try to determine how much water should be in rivers. With its range of river and ecosystem conditions, growing population, and high demands on water, Texas is representative of instream flow challenges across the United States, and its instream flow program may be a model for other jurisdictions. Three state agenciesâ€"the Texas Water Development Board (TWDB), the Texas Parks and Wildlife Department (TPWD), and the Texas Commission on Environmental Quality (TCEQ)â€"asked a committee of the National Research Council (NRC) to review the Programmatic Work Plan (PWP) and Technical Overview Document (TOD) that outline the state's instream flow initiative. The committee suggested several changes to the proposed plan, such as establishing clearer goals, modifying the flow chart that outlines the necessary steps for conducting an instream flow study, and provide better linkages between individual studies of biology, hydrology and hydraulics, physical processes, and water quality.
